Can I install a switch and outlet wire in the same hole?

Yes, you can put both wires in the same hole. Just make sure the wiring is protected in the center of the framing. Install Safety Nail Plates if needed. See the Wiring Projects link below for some pictures of installing electrical wiring and safety plates…..

Electrical Tip

The Safest Way to Test Electrical Devices and Identify Electric Wiring!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
